On their product page no AV1 and also on the RK3568 link you provide, so typo I think 😓

Jean-Luc Aufranc (CNXSoft)

Sorry about that. That was from the AAEON RICO-3568 article, as I copied info from their product page, and Debashis copied that again in that article. I’ve corrected both articles.

RK3566/RK3568 does not support AV1.
